Keep your work van planted over every load with the KYB shock absorber, MPN 554348 — a Gas-a-just high-pressure monotube gas shock built for the rear position. It installs as a direct-fit replacement for the listed applications: 2003-2024 Chevrolet Express 2500, 2006-2024 Chevrolet Express 3500, 2009-2024 Chevrolet Express 4500, 2003-2024 GMC Savana 2500, 2006-2024 GMC Savana 3500, and 2009-2024 GMC Savana 4500. See the Buyer's Guide tab for engine-level detail.

  • High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
  • Triple chrome plated piston rod: ultra-smooth to reduce seal wear, since fluid leaking can be a cause of shock failure.
  • Higher gas pressure: the KYB Gas-a-just responds quickly to help improve steering response.
  • Built for GM vans: components and valving designed specifically for these vans, adding up to 25% more damping over original-equipment shocks for vehicles that work, tow, and run larger, heavier tires and wheels — and helping keep Electronic Safety Systems performing as designed.

Unlike a traditional twin-tube, this Gas-a-just runs an air-free hydraulic piston/valve chamber for control plus a separate high-pressure nitrogen chamber with a floating piston for a comfortable ride during normal driving.
